WATER-GAG E.

SPECIFICATION fams To all whom it may concern:

Be it known that I, THADDEUS GALVIN, of Detroit, county of Wayne, State of Michigan, have invented a new and useful Improvement in Water- Gages; and I declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which form a part of this specification.

My invention consists of of devices and appliances fied, and"more particularly claims.

In the drawings, Figure 1 is a front elevation of an apparatus embodying my invention. Fig. 2 is a view in perspective. Fig. 3 is a variation of the guard. Fig. 4 is a sectional view of the valve.

Heretofore it has been customary to make the guards for the glass tubes in water-gages of a straight rod screw-cut at the top and provided with a knob adjusted upon the screw-cut. end to form a head whereby it is supported in the sockets; but it has been found that the guards as thus constructed not infrequently work loose and are thrown out of place, by I11 portable engines they are liable to be thrown out and lost. It has also been customary to provide said gages with a ground escape-cock, which soonbegins to leak and easily wears out.

It is the object of my invention to remedy these difficulties, first, by providing an improved guard for water-gages; second, by prothe combinations hereinafter specipointed out in the viding an improved valve for the same.

To this end, as shown in thedrawings, A is a glass tube of any ordinary water-gage, and B and B are the top and bottom glass connections.

0 represents the arms supporting the guard, provided with the guard-sockets at c.

' D is a spring-guard, constructed of a single rod of metal or other suitable material, bent midway of its length and passed into the sockets at c on the arms 0. It is found that a guard constructed in this manner has sufficient elasticity to hold itself in place, whereas in the old way it was necessary to cut the threads part of Letters Patent-N0. 279,144, dated June 12, 1883, Application filed August 5, 1882. (No model.)

upon the ends of the rods and to make the knobs fitted for adjustment thereon.

It is evident that my improved guard is simpler, more easily and more cheaply constructed, as no screw-threads are required to be cut, and the knobs, which are more expen sive than the rods, are entirely dispensed with, while at the same time the guard works more satisfactorily. By this invention, moreover, lighter wire can be used in the construction of the guards, and more strength can be obtained, if desired.

Fig. 3 is D, where, to insure greater elasticity and consequent pressure of the guard against the side of the sockets to hold it more firmly in place, the guard is constructed with a more complete curve midway of its length, the two ends of the rod lapping by each other.

It will be obvious that either of these or other forms of construction may be used without departing from the principle of my inven tion.

It is also evident that more than one of these guards may be used in a water-gage, if desired, as shown in Fig. 2.

E is the valve-stem, constructed with alongitudinal passage, e, which communicates with a transverse perforation or orifice adjacent to the inner end of the valve-stem in such manner that as soon as the said stem is adjusted and the valve commences to leave its seat the water in the glass tube is immediately permitted to discharge through the transverse perforation or orifice into the longitudinal passage in the stem, from which it escapes at the outer end thereof. This valve does the duty of the ordinary ground escape-cock with greater satisfaction, is more easily repaired, and lasts longer. I am aware that a similar valve has that it has ever been used in this connection.

\Vhat I claim is- 1. An improved watergage composed, es-

sentially, of the glass indicating'tube A, the

end'connections,'l3 and B, having the attached laterally-projecting arms C, each provided with perforations at opposite sides of the inlength and a variation of my improved guard .dicating-tube to form sockets 0, and the spring. guard D, consisting of a rod bent midway its inserted through the sockets in been used in other places; but I am not aware both the top and bottom arms, where it is re a watergage, of the lower end connection, tained by lateral spring-pressure, substantially composed of a casing, B attached to the tube I 5 as described. 7 and having the interior valve-seat, b, and the 2.
